"Many people are great singers/musicians and sound great on a CD, but lack performance skills and stage presence, you cannot judge this on a CD"
And some are better live than they are on CD...
All of which reminds me that some organisers actually prefer a demo CD to contain material from a live performance, and I must remember to take my flash-memory recorder with me to some gigs and see if we can get a good take.
